Hello all. I have a question to the forum. I have a 2013 20sl with a 2012 Yamaha F70. Nice boat and engine. 25" pontoons (2), with the short center fuel pod. Engine is on lowest hole. I talked with Benny and they said since I have the upgraded toons my max hp is 90 rather than the sticker 70hp. I asked for prop recommendations from them and they suggested the 14x11 dual thrust elephant ear-looking prop. So I bought it. Looks like a rooster with socks, but it works. I jump up to almost max speed in a second with almost no throttle. Like 1/4. But, if I push it much further, it'll peg out at 7500 rpm. No, I don't run it like that, but it leaps to 7500. It feels like I'm ventilating big time, but I am trimmed all the way in. The vent plate is about an inch below the fuel pod bottom. So, 3 possibilities in my brain. 1, the pitch isn't right. But, I'd have to add 2 or 3 inches to even get close to 6000. 2, because of upgraded toon and extra flotation, engine is too high (boat floats higher so transom is too high) , or 3, the fuel pod is cramming soft water into prop. None of those are mutually exclusive. I am not inclined to do much with any of the variables until I gleen max wisdom from you guys.
Thanks
